//Here, our set of test scores is represented as an array (x) //of N doubles. For more information on doubles, see "What are doubles?"

//"What are doubles?" //Doubles are floating-point numbers in the C++ //programming language. The important //thing to know about these is that their remainders do not truncate //in division. So if 3.0 is a floating-point number, then //3.0 / 2 = 1.5. In "integer division", the remainder would //have truncated and the answer would have been 1).
